引外し装置。 An electromagnet to which a circuit voltage is applied, a plunger that is attracted and held by the electromagnet when the circuit voltage is equal to or higher than a reference voltage and released from holding when the circuit voltage falls below a reference value, and a frame with a standby position and an operating position. an actuating lever provided to reciprocate and rotate between the two; a lever spring that biases the actuating lever to rotate toward the operating position; an engaging portion which is movably provided and is rotated to a set position with the plunger being attracted and held, and engages one end of the actuating lever to restrict the actuating lever to a standby position against the lever spring; at the other end, and when the plunger is released from the electromagnet and the latch is allowed to rotate in one direction from the set position, the actuating lever moves from the engaging portion of the latch to the latch. a trip can that is disengaged by a biasing force of a lever spring and moved to a trip position based on the rotation of the actuating lever from a standby position to an operating position, thereby shifting the circuit breaker body to a breaking state; A reset lever is provided on the frame so as to be able to rotate in conjunction with the movement of the plunger, and the reset lever is rotated in one direction by being moved as the circuit breaker main body shifts to the disconnected state. a trip bar for moving the plunger to a position where it can be attracted to the electromagnet again; An undervoltage tripping device for a circuit breaker, comprising a linkage mechanism for returning and rotating against a spring.
